Solandra

At its core, Solandra is a tight integration of Solr and Cassandra, meaning within a single JVM both Solr and Cassandra are running, and
documents are stored and disributed using Cassandra's data model.

Getting started:

The following will guide you through setting up a single node instance of Solandra.

From the Solandra base directory:

mkdir /tmp/cassandra-data
ant
cd solandra-app; bin/solandra

Now that Solandra is running you can run the demo:

cd ../../reuters-demo
./1-download_data.sh
./2-import_data.sh
While data is loading, open the file ./website/index.html in your favorite browser.

Embedding in an existing cassandra distribution

To use an existing Cassandra distribution perform the following steps.

Download your Cassandra distribution

Unzip it the directory of your choice

Run the following solandra ant task to deploy the necessary files into the unzipped dir

ant -Dcassandra={unzipped dir} cassandra-dist

You can now start Solr within Cassandra by using $CASSANDRA_HOME/bin/solandra command. Cassandra now takes two optional properties: -Dsolandra.context and -Dsolandra.port for the context path and the Jetty port.

Limitations

Solandra uses Solr's built in distributed searching meachanism.
Most of its limitations are covered here:
